ABSTRACT:
A method for automatically rectifying business card presentation angle is described. The method is applicable to a mobile electronic device to automatically rectify a presentation angle of a shot business card image. Firstly, maintain character pixels of the shot business card image, and divide the character pixels into character groups by determining whether the pixel pitch is larger than a predetermined value. Next, obtain a first axis and a second axis of the character groups. After that, calculate an included angle formed between the first axis and the second axis, and adjust the oblique character groups through angles obtained for correction. Then, adjust aspect ratios of all the character groups after angle correction according to appropriate character aspect ratios, to make the displayed font seem normal. Finally, generate a corrected business card image according to the character groups after correction.
